I have a Dell Inspiron 9400 with Windows XP Home Edition that just will not launch. Says a problem has been detected and windows has been shut down to prevent damage: UNMOUNTABLE_BOOT_VOLUME. I have tried everything short of using a reboot/repair disk (I don't have one). Any help would be appreciated. How can I 1) reboot safely and 2) access and save some of the directories on the hard drive as I need to save some of the data on the hard drive to another media.
